California voters passed a ballot measure to legalize the recreational use of marijuana, giving a big boost to the campaign to end the drug's national prohibition.

Adults older than 21 can legally possess up to an ounce of marijuana and grow six plants.

California was one of five states where votes were considering the legalization of recreational marijuana Tuesday. Four other states were considering measures to legalize medicinal marijuana.

So far, voters in Florida and North Dakota have also passed marijuana measures Tuesday.

Collectively, it's the closest the U.S. has ever come to national referendum on marijuana.

11:15 p.m.

Arizona voters have booted Sheriff Joe Arpaio from office in his bid for a seventh term after his legal problems in a racial profiling case culminated in a criminal charge two weeks before Election Day.

The 84-year-old Republican became a national figure by cracking down on illegal immigration and forcing jail inmates to wear pink underwear. He lost to Democrat Paul Penzone on Tuesday.

The race became a referendum on Arpaio's legal woes. Federal prosecutors brought a contempt-of-court charge stemming from his defiance of a judge's order to stop carrying out patrols targeting Latinos.

Arpaio has faced criminal investigations in the past without being charged or losing his seat. That changed Tuesday despite a devoted base of supporters and strong fundraising, mainly from out-of-state donors.

He still faces the possibility of jail time.

11:11 p.m.

Donald Trump has won battleground North Carolina and its 15 electoral votes.

The victory in Tuesday's elections brings the billionaire's electoral vote total to 216. Democrat Hillary Clinton has 197.

North Carolina was one of the hardest-fought contests of the election and is one of the map's newest swing states. It consistently went for Republicans until Barack Obama captured it in 2008. Republican Mitt Romney narrowly won the state in 2012.

At least 270 electoral votes are needed to win the presidency.

11:06 p.m.

Hillary Clinton has won Oregon.

The Democratic nominee on Tuesday was awarded its seven electoral votes.

Clinton now has 197 electoral votes. Her Republican opponent Donald Trump has 201.

Several key battleground states have yet to be won.

11 p.m.

Hillary Clinton has won California and Hawaii. Donald Trump has won Idaho's four electoral votes.

The results in the West bring Clinton's electoral vote total to 190 and Trump's to 201. It takes 270 votes to win the presidency.

The results were not surprising. California, with 55 electoral votes, has voted for Democrats beginning in 1992. Hawaii has chosen Democrats consistently since 1988.

Idaho has voted for Republicans beginning in 1968.

10:21 p.m.

Hillary Clinton has won New Mexico and its five electoral votes.

That brings her electoral college vote total in Tuesday's election to 109. Republican Donald Trump has 140 votes.

10 p.m.

Republican Gary Herbert has been re-elected governor of Utah.

Herbert had a strong advantage in Tuesday's elections and was considered the favorite in the conservative state. But many Utah conservatives were not enthused about GOP presidential nominee Donald Trump. And Herbert had vacillated on his support for the New York billionaire.

Herbert has been in office since 2009 and had been challenged by Democrat Mike Weinholtz, a wealthy former CEO of a medical staffing company.

10 p.m.

Donald Trump has won Montana.

The Republican presidential nominee on Tuesday was awarded the state's three electoral votes.

The result was not a surprise, as Montana was considered a safely Republican state.

Preliminary exit polls show the racial divides that were expected to define the 2016 presidential election.

Polls conducted for national media by Edison Research show Republican Donald Trump winning a majority of white voters while Democrat Hillary Clinton is drawing support from about three out of four nonwhite voters.

Trump's support is strongest among whites without a college degree. He's winning nearly two-thirds of them. Whites with college degrees are split between Trump and Clinton. Trump is winning both among white men and white women, though his margin is much higher among men.

Clinton's strongest support comes from African-Americans. She's winning about nine out of 10 black voters. She's winning about two out of three Hispanics and Asian-Americans.

9:30 p.m.

Republican Donald Trump is maintaining Republicans' advantage among white voters nationwide, but perhaps not by the usual margin that the party's nominees have enjoyed.

Preliminary exit polls of voters who have already cast presidential ballots show Trump winning a majority of whites. He has not quite reached the roughly six-out-of-10 share that Mitt Romney notched four years ago in his unsuccessful challenge of President Barack Obama.

The difference appears to come among white women. Trump is posting about the same, if not a slightly wider margin among white men as Romney did in 2012. But his lead over Clinton among white women appears to be in single digits, short of Romney's double-digit advantage four years ago.

9:28 p.m.

Donald Trump has won Louisiana and its eight electoral votes.

That extends his Electoral College total in Tuesday's elections to 137, compared with Hillary Clinton's 104.

History was on Donald Trump's side in the state. Louisiana hasn't given its electoral votes to a Democrat since Bill Clinton won 52 percent of the vote two decades ago.

That brings his electoral vote total in Tuesday's election to 129. Democrat Hillary Clinton has 97.

It takes 270 votes to win the presidency.

The result was expected. Earlier polling showed Trump leading Clinton by double digits in the state where she served as first lady for 12 years while her husband was the governor.

The once reliably blue state has turned red in recent years. Republicans now control all of Arkansas' statewide and federal offices, as well as a majority of seats in both chambers of the state legislature.

Arkansas has backed the Republican candidate for the White House in every election since 1980 — except for years when Bill Clinton was running for president.

9:05 p.m.

Hopeful Hillary Clinton supporters have gathered on a Brooklyn street corner they expect to be prophetic: The intersection of President and Clinton Streets.

Photos and video posted on social media Tuesday show hundreds of people gathered for a block party where the streets cross.

Organizers have set up a large screen to stream election coverage. A food truck is dispensing tacos to the crowd.

The street signs in the intersection have been an attraction all Election Day for Clinton boosters snapping selfies.

It is just under a mile from Clinton's national campaign headquarters in Brooklyn.

9:05 p.m.

Polls in Colorado will close at 7 p.m. MST after a judge denied the Colorado Democratic Party's request to extend voting by two hours.

The head of the Colorado Democratic Party argued that voting hours should be extended to account for a 29-minute computer glitch Tuesday afternoon. The statewide glitch affected same-day voter registration and caused some voters to have to cast provisional ballots.

The Secretary of State opposed the extended hours. Deputy Secretary of State Stephanie Staiert says no one was prevented from voting because of the glitch.

9:01 p.m.

Republican Doug Burgum has won the North Dakota governor's race.

The Fargo businessman and onetime Microsoft Corp. executive was considered a shoo-in in Tuesday's election. He defeated Democrat Marvin Nelson.

The matchup focused on qualifications to lead the socially conservative state amid declining oil and crop revenues.

Burgum has stuck to themes of budget discipline, job creation and opposition to tax increases. Nelson has been highly critical of deep cuts to government agencies and a massive raid on the oil-rich state's savings to make up for a more than $1 billion budget shortfall due to a drop in oil drilling and depressed crude prices

9 p.m.

Donald Trump has won Texas, North Dakota, South Dakota, Wyoming, Kansas and Nebraska while Hillary Clinton has won New York and Illinois.

Trump also on Tuesday won two of Nebraska's congressional districts. In the state that awards by congressional district, one remains too close to call.

Trump was awarded Texas' 38 electoral votes, the second-largest prize on the map. He also won six from Kansas, four from his victories in Nebraska and three apiece from Wyoming, North Dakota and South Dakota.

Clinton was awarded 20 from Illinois and 29 from New York, the state both candidates call home. Trump had declared he would try to win New York but never mounted a serious effort there.

The Republican nominee now has 123 electoral votes. Clinton has 97.

8:55 p.m.

Hillary Clinton is watching election returns with a collection of close campaign aides and her family in a suite at the Peninsula New York, a luxury hotel in midtown Manhattan.

Aides say the group is snacking on salmon, roasted carrots and fries — along with vegan pizza and crème brulee for former President Bill Clinton, who's careful about his diet. Her granddaughter, Charlotte, is wearing a dress emblazoned with the campaign logo.

Clinton and her husband have also been working on her election night remarks with her speechwriters.

Later Tuesday evening, they'll move to the Jacob K. Javits Convention Center in New York City for her election night party. It's a building with a glass ceiling — a nod to the historic moment.

8:51 p.m.

Donald Trump has won Mississippi and its six electoral votes.

That brings his Electoral College total in Tuesday's election to 66, compared with Hillary Clinton's 48.

The outcome was not unexpected. Mississippi has voted for Republicans in every presidential election starting with 1972, with the exception of Democrat Jimmy Carter in 1976.

8:40 p.m.

Hillary Clinton has won Rhode Island and its four electoral votes.

That brings her total Tuesday to 48, compared with Donald Trump's 60.

It takes 270 electoral votes to win the presidency.

Rhode Island has voted for Republicans for president only four times since 1928.

In 2012, President Barack Obama defeated Republican Mitt Romney in the state by about 27 percent.

__

8:33 p.m.

Exit polls conducted by Edison Research for national media outlets suggest Hillary Clinton is still struggling with white voters who have put Georgia in the Republican column for every presidential election but one since 1980.

Exit polls in Virginia show Clinton and Republican Donald Trump split white Virginia voters with college degrees. In North Carolina, Trump apparently won a slight majority of college-educated whites. But in Georgia, whites with college degrees sided with Trump by more than 2-to-1.

Among whites with no degree, the gaps were even wider. Trump won about two out of three of those voters in North Carolina and Virginia. In Georgia, he won about four out of five.

8:27 p.m.

Donald Trump has won Alabama and its nine electoral votes after Sen. Jeff Sessions endorsed the billionaire candidate.

That brings Trump's total in the Electoral College to 60 votes, to Clinton's 44 votes.

It takes 270 votes to win the presidency.

The results continue the state's streak of voting for Republicans every presidential election since 1980.

8:13 p.m.

Donald Trump has won Tennessee and its 11 electoral votes.

Tuesday's vote is the fifth presidential contest in a row in which the state voted for the Republican candidate. That includes the 2000 election, when native son Al Gore lost the state to Republican George W. Bush.

It takes 270 votes to win the presidency.

6:05 p.m.

Guests are beginning to gather at Donald Trump's election night party in midtown Manhattan.

The GOP nominee is holding his event in the grand ballroom of a midtown Hilton hotel, where a stage has been decorated with dozens of American and state flags.

Trump's campaign has also set up museum-style glass displays around the venue holding campaign merchandise, including his iconic "Make America Great Again" hats and pins.

7:30 p.m.

Republican Donald Trump has won West Virginia and its five electoral votes.

The Mountain State was one of the billionaire's biggest supporters in the Republican primary. He is popular for promising to bring back coal jobs. Hillary Clinton had largely been largely shunned for making comments perceived as an affront to the industry.

The dynamic has resulted in one of the few states where Republicans didn't shy from the brash businessman and instead looked to ride his coattails. Many Democrats for congressional and other races scrambled to distance themselves from Clinton and refused to endorse her.

West Virginia has voted for Republican presidential candidates in each of the last four presidential races.

It takes 270 electoral votes to win the presidency.

7:15 p.m.

Philadelphia District Attorney Seth Williams says he has found no evidence of fraud or intimidation at the city's polls despite Republican candidate Donald Trump's warnings about voter fraud.

Williams says no major problems have emerged among the 68 complaints his office investigated during the first half of Election Day.

Meantime, several Pennsylvania counties are reporting a handful of complaints about touchscreen machines switching votes. They say the machines are quickly being re-calibrated to fix the problem.

Pennsylvania Secretary of State Pedro Cortes says the GOP reported problems with about 25 machines, out of nearly 24,000 deployed statewide. He says in all cases votes ended up being recorded correctly.

State GOP Chairman Rob Gleason says he doesn't see anything "nefarious" in the apparent vote switching on older machines.

7:10 p.m.

Vast divides of race, gender and education are keeping the presidential race in two tightly fought southern states close shortly after polls close.

In both Virginia and Georgia, about 9 in 10 black voters and two-thirds of Hispanics backed Clinton, while most whites backed Trump.

That's according to exit polls conducted by Edison Research for national media outlets.

In Georgia, large majorities of whites with and without college degrees backed Trump. In Virginia those two groups diverged. Whites without a college degree backed Trump by a large margin, while those with a degree split their votes between the two major-party candidates.

Women in both states were far more likely than men to back Clinton. Majorities of women in both states said Trump's treatment of women bothers them a lot.

7 p.m.

Republican Donald Trump has won Kentucky and Indiana while Democrat Hillary Clinton has won Vermont.

Trump was awarded Kentucky's eight electoral votes and Indiana's 11. Vermont gives Clinton three. These are the first states to be decided Tuesday in the 2016 general election.

The wins were expected.

Vermont has voted for a Democrat every election since 1988, while Kentucky has gone Republican every cycle since 2000.

Indiana is normally a Republican stronghold but went for President Barack Obama in 2008. The Republicans captured it again in 2012 and Trump's running mate, Mike Pence, is the state's governor.

The winning candidate needs 270 electoral votes.

6 p.m.

More than half of Americans who went to the polls earlier Tuesday say Democratic nominee Hillary Clinton has the temperament to serve as president. About a third of voters say the same about Republican nominee Donald Trump.

But neither candidate can claim a mandate as the honest candidate according to the preliminary results of exit polling conducted by Edison Research for The Associated Press and television networks.

About six out of 10 voters say they don't view Clinton as honest. About the same proportion say Trump isn't honest. About three out of 10 voters say they believe neither candidate is honest.

As for what percentage of voters think both nominees are honest, that number is in single digits.

5:55 p.m.

The Colorado Secretary of State's voter registration system went down for nearly 30 minutes during midday voting Tuesday.

The failure forced in-person voters to cast provisional ballots, and some county clerks were unable to process mail ballots that needed to have the signature verified.

Tauna Lockhart, spokeswoman for the state information technology office, says the system came back up about 3:20 p.m. She says the incident is under investigation by state officials, but there is no evidence the network was hit by hackers.

She says the IT office has been monitoring its network for activity and said "there were no blips or anything."

5:40 p.m.

Police say they arrested two women after they took off their tops in protest at the Manhattan polling place used by Donald Trump.

The disruption occurred Tuesday morning at a grade school gym about two hours before Trump arrived.

The women began shouting and took off their tops to reveal anti-Trump slogans painted across their bare chests before police escorted then away.

They were released after being given summonses for electioneering, a violation of rules outlawing political activity at polls.

5:37 p.m.

At least 2,000 people are already waiting inside the New York City convention center where Hillary Clinton is scheduled to hold her election night party.

Most people are sitting on the floor in an area the size of an airplane hangar. A handful of women are wearing pantsuits to honor Clinton.

Barnard College senior Madeline Walsh is wearing a black pantsuit. She says the garment means its wearer is more than just a woman.

5:35 p.m.

A spokesman says former President George W. Bush did not vote for Republican Donald Trump or Democrat Hillary Clinton.

Freddy Ford says the most recent Republican president voted "none of the above for president and Republican down-ballot." That means Bush voted for Republicans in congressional and local races.

It's not a complete surprise. The Bush family includes the two most recent Republican presidents but neither endorsed nor campaigned for the billionaire businessman who captured the party's nomination. Former Florida Gov. Jeb Bush was a one-time favorite to win the GOP presidential nomination until Trump got into the race and branded him with a name that stuck: "Low energy."

5:30 p.m.

Preliminary presidential exit polls results suggest that a clear majority of Americans going to the polls Tuesday have at least a moderate amount of confidence that votes will be counted accurately.

About half of those polled for The Associated Press and television networks told Edison Research they are very confident in the results. Another third said they are somewhat confident.

Fewer than one out of five say they're not very confident or at all confident in the vote count.

Republican presidential nominee Donald Trump has railed against the electoral system. He's called it rigged and suggested without evidence there is widespread voter fraud that could affect the outcome.

5:25 p.m.

Just more than half of voters going to the polls Tuesday approve of the job President Barack Obama is doing. But a majority is still upset with the way the federal government is working.

That's according to preliminary results of the exit poll conducted for The Associated Press and television networks by Edison Research.

Just under half of those surveyed say they're dissatisfied with the government's performance. About a quarter say they're angry.

About four out of 10 voters said the top quality they're looking for in a candidate is change. That outranks good judgment, the right experience and caring about people like you as the preferred qualities in a president.

5:22 p.m.

Arizona's most populous county may not know its vote totals today, which could leave in doubt the presidential race in the traditionally Republican-voting state.

Maricopa County, which includes Phoenix, expects to have more than 350,000 uncounted early ballots by the time the polls close. Roughly 1.1 million voters in the metropolitan county had returned early votes as of Tuesday, up 140,000 from 2012.

Election workers had counted roughly 800,000, leaving more than 200,000 to count. Roughly 150,000 are expected to have been dropped off at polling sites around the county.

Elizabeth Bartholomew, communication manager for Maricopa County Recorder's office, says, "If there's a large enough gap in votes, you might not be able to call some races."

Republican Donald Trump and Democrat Hillary Clinton were running neck-and-neck in Arizona, carried by Republicans in all but one election since 1952.

5:20 p.m.

Neither Donald Trump nor Hillary Clinton is able to claim favorable standing with a majority of the U.S. electorate.

Six of 10 voters say they are somewhat bothered or bothered a lot by Clinton's use of a private email server while secretary of state, according to preliminary results from exit polling conducted by Edison Research for The Associated Press and television networks.

More than seven out of 10 presidential voters say they are irked by Trump's treatment of women.

Trump hammered Clinton for how she handled classified information at the State Department. The FBI twice said it had no cause to pursue criminal charges.

Fewer than half of voters who cast presidential ballots say they made their choice out of a strong preference for their candidate.

That's according to preliminary results of the exit poll conducted for The Associated Press and television networks by Edison Research.

The early exit polls found both Republican Donald Trump and Democrat Hillary Clinton are viewed unfavorably by a majority of the presidential electorate. A majority of the electorate also distrusts each of them.

A third of voters said they have reservations about the candidate they backed. A quarter of voters say their vote was mostly about opposing another candidate.

In 2012, the presidential electorate was more optimistic about their choices. That year, about two out of three voters said they strongly backed their candidate.

5:05 p.m.

Seven in 10 Americans going to the polls Tuesday say they think immigrants now in the country illegally should be allowed to stay. Just a quarter say they should be deported.

More than half say they oppose building a wall along the Mexican border to stop illegal immigration, according to preliminary results from the exit poll conducted for The Associated Press and television networks by Edison Research.

But immigration isn't necessarily at the top of the minds of most voters. Just 1 in 10 say immigration is the most important issue facing the country.

Republican Donald Trump made cracking down on immigration a top item on his agenda.

5 p.m.

Most voters going to the polls Tuesday have a pessimistic view of the U.S. economy.

According to preliminary results of an exit poll conducted by the Associated Press and television networks by Edison Research, about 6 in 10 describe the state of the economy as not so good or poor.

But that economic unhappiness isn't as high as it was in 2012, when three-quarters called the economy not so good or poor.

Among voters today, 3 in 10 say their personal financial situation has gotten better in the last four years, while nearly as many say it's gotten worse.

More than half of voters say the economy is the most important issue facing the country, over terrorism, foreign policy and immigration.

4:50 p.m.

Authorities have beefed up Election Day security for Donald Trump by parking dump trucks filled with sand outside his Trump Tower building on Fifth Avenue.

Police said Tuesday that similar precautionary measures were being taken at other sites around midtown Manhattan where Trump and Hillary Clinton plan to spend election night.

Authorities say the heavy trucks could block an attempted car bombing. They say there are no confirmed terror threats.

The NYPD had previously said it will deploy more than 5,000 police officers to keep order on election night. The deployment also includes police helicopters, mobile radiation detectors and bomb-sniffing dogs.

4:40 p.m.

A state judge in Nevada has denied a request from the Donald Trump campaign to preserve ballots and voting materials related to what the campaign alleges were irregularities during early voting.

Clark County District Court Judge Gloria Sturman said Tuesday that making the names of poll workers part of the court record could expose them to "public attention, ridicule and harassment."

She says the county registrar is already required to keep the records, and the Nevada Secretary of State is responsible for investigating the complaint.

Trump campaign attorney Brian Hardy told the judge he wants to preserve records from the final day of early voting at four locations in the Las Vegas area.

The campaign says allowing people to vote past closing time was illegal, but the county says they were accommodating people already in line.

The Trump campaign lodged a separate complaint with the secretary of state.

4 p.m.

A software glitch that indicated scores of voters showing up at the polls had already cast ballots has led to voting delays in one of North Carolina's most heavily Democratic counties.

North Carolina Board of Elections lawyer Josh Lawson says officials in Durham County quickly concluded that there was a problem with their electronic poll books and began relying on paper rolls to confirm voter registrations. Attempts to vote twice are rare.

Lawson says there's no indication "nefarious activity" caused the computer problems. Rather, he said it could have been a failure to clear out caches of votes cast during the primaries.

About two dozen other counties using the same software have not reported problems.

Lawson said those in line when the polls close will still be allowed to vote.

3 p.m.

President Barack Obama is hitting the radio airwaves to encourage Americans to go to the polls to vote for Hillary Clinton.

The White House said Obama gave Election Day interviews to six radio stations that target listeners in Orlando, Detroit and Philadelphia. The cities are in states where the race is believed to be close between Clinton and Republican Donald Trump.

Obama told syndicated host Jana Sutter that continuing the work of the past eight years depends on having a "steady, smart, serious" president follow him into office.

He praised Clinton and reiterated his view that Trump is unfit to be president.

2:45 p.m.

Donald Trump is rekindling his unsubstantiated concerns about a rigged election system.

Asked Tuesday afternoon on Fox News if he would accept the election results, Trump continued to demur.

The Republican presidential nominee said: "We're going to see how things play out."

He said. "I want to see everything honest."

Concerns about voter intimidation and fraud led to a flurry of lawsuits in the run-up to Election Day. New voter regulations in more than a dozen states also held the potential to sow confusion at polling places.

But at least in the early going, most of the problems at polling places appeared to be routine — the kinds of snags that come every four years, including long lines, machines not working properly, and issues with ballots or voter rolls.

2:20 p.m.

It could be the first lawsuit of Election Day. Donald Trump's campaign is alleging polling place "anomalies" during early voting in the Las Vegas area last week.

A lawsuit filed Tuesday in Nevada court asks that records from four early voting spots that allegedly stayed open too late last Friday be impounded and preserved.

Long lines kept polls open past the 7 p.m. posted closing time at locations that included a Mexican market and several shopping centers. Officials say at one site, the last voter cast a ballot after 10 p.m.

Criticism is also coming from state Republican Party chief Michael McDonald.

But Democrat Hillary Clinton's campaign is dismissing the Nevada case in a Twitter message, calling it "a frivolous lawsuit."

1:30 p.m.

President Barack Obama says his faith in the American people hasn't wavered.

Asked whether he was feeling nervous about the presidential election outcome, Obama said "I think we'll do a good job" as long as the American people vote.

Lines were long in some areas as voters chose between Democrat Hillary Clinton, Republican Donald Trump and some third-party candidates.

Obama said he hopes everyone has "voted early. If not, get out there."

Obama supports Clinton and voted early last month in his Chicago hometown. He spoke while walking from the White House residence to the Oval Office, following his Election Day tradition of playing basketball with friends.

1:25 p.m.

Eric Trump may have broken New York state law by tweeting a photo of his completed ballot.

The second son of Republican presidential candidate Donald Trump tweeted a photo of a ballot with the oval over his father's name filled in on Tuesday.

The tweet said "It is an incredible honor to vote for my father! He will do such a great job for the U.S.A!" It was later deleted from Trump's Twitter account.

An 1890 New York law bans voters from showing marked election ballots to others. A federal judge ruled last week that the law applies to social media posts.

Representatives for Eric Trump and the New York City Board of Elections did not immediately respond to calls seeking comment.

1:20 p.m.

It was a quick trip to the voting booth for Donald Trump's running mate on Tuesday.

Indiana Governor Mike Pence was joined by his wife, Karen, as they voted in Indianapolis. The couple encountered no lines and spent about five minutes filling out their ballots.

Pence told a small crowd afterward that he was grateful for the "support and prayers of people all across the United States" and he pledged a more prosperous America with the Trump-Pence ticket.

Pence and his wife voted in a precinct that has leaned liberal in past elections.

1:15 p.m.

Norwegian Prime Minister Erna Solberg says a victory for Hillary Clinton on Election Day would be "inspirational" to young women. But she joked that this wouldn't lead to a "global girlfriends' network."

At a Berlin press conference with German Chancellor Angela Merkel Tuesday, Solberg said a female U.S. president would show women that politics isn't "something that belongs to men."

Merkel echoed Solberg's comments about creating more of a global balance between men and women in power. She declined to comment on whom she'd like to win the election, pointing out that the "trans-Atlantic partnership is certainly a prerequisite for us, especially cooperation in NATO."

Republican Donald Trump has said that he may revisit the longstanding NATO alliance if elected.

12 p.m.

Billionaire Warren Buffett is devoting part of Election Day to get-out-the-vote efforts — as he helps drive voters to the polls on a trolley he hired.

The longtime Democrat had promised to help boost turnout at a Hillary Clinton rally in Omaha in August. Buffett says some people have it tougher than others — maybe an illness or trouble with their car. He says he wants to do his part so everyone gets a chance to vote.

More than 1,000 people have volunteered to help Buffett drive voters to the polls.

Buffett is a supporter of Clinton's, but on Tuesday he declined to talk about that. Instead, he said he just wanted to encourage everyone to vote regardless of party affiliation.

11:40 a.m.

President Barack Obama says on Twitter that "progress is on the ballot" Tuesday.

He's urging his more than 11 million Twitter followers to "go vote." He also says they should make sure that their friends, family and everyone they know votes, too.

Obama has campaigned aggressively to help elect Democrat Hillary Clinton.

He used the "progress is on the ballot" line at many of the get-out-the-vote rallies he headlined for his former secretary of state.

Utah Director of Elections Mark Thomas says a programming problem has affected all voting in Washington County, but so far appears it appears limited to that county.

He says about 52,000 registered voters there have yet to cast their ballots.

Election workers are trying to fix the computer problem and hope they can start using the voting machines later in the day.

Thomas says officials were prepared with backup paper ballots. But he said they will need to print more if the problem persists.

There are about 80,000 total registered voters in Washington County. Some 28,000 have already cast their ballots through early voting.

11:25 a.m.

Donald Trump has voted in New York City.

Hundreds of onlookers watched as Trump, his wife Melania, daughter Ivanka, and son-in-law Jared arrived Tuesday morning at their polling place at a public school on Manhattan's East Side.

Trump said: "it's a great honor, a tremendous honor" to be casting his ballot.

He said he's feeling confident about the outcome, citing "tremendous enthusiasm."

As for his longstanding concerns about voter fraud, he says. "We're always concerned about that."

His final message to voters: "Make America great again. That's all it is. That's what it's all about."

11:05 a.m.

Hillary Clinton is getting some quirky questions in Election Day radio interviews.

Clinton phoned WKZL in North Carolina and was asked whether she prefers Pepsi or Coke? Coke, said Clinton.

Toilet paper — over the top or under the bottom of the roll? "Usually over, but I can live with under," quipped Clinton.

And, sleeping arrangements. Clinton told WXKS in Boston that she won't switch which side of the bed she sleeps on if elected president. The White House will have to put the storied presidential phone on her side, not on the side that her former president husband sleeps on.

She said: "I have my side, and it works very well for us." As for Bill, she said, "I think he'll be happy to let me answer it."

10:55 a.m.

WikiLeaks chief Julian Assange says he wasn't trying to influence the U.S. presidential election when his organization published hacked emails from Hillary Clinton's campaign.

In a statement Tuesday, Assange denied he was trying to support Green Party candidate Jill Stein or take revenge for the jailing of former U.S. intelligence analyst Chelsea Manning.

Manning was sentenced to 35 years in prison for leaking secret U.S. government documents to WikiLeaks.

Assange suggests WikiLeaks would publish material on Clinton's Republican rival Donald Trump, if it received appropriate material and judged it newsworthy.

Assange said Wikileaks has not yet received information on the campaigns of Trump, Stein or other candidates "that fulfills our stated editorial criteria."

9:55 a.m.

As voters cast their ballots for president, some are convinced, while others are holding their breath.

In Indianapolis, 50-year old homemaker Ranita Wires said she voted for Hillary Clinton because she trusts her, but said "this has been the worst," and she's "so glad it's over."

Craig Bernheimer voted for Donald Trump at his local polling station in Tulsa, Oklahoma early Tuesday, saying it has more to do with "what the other didn't bring."

New Mexico truck driver Richard Grasmick said he admired Libertarian candidate Gary Johnson and intended to vote for him, but grew disillusioned by Johnson's televised flubs on foreign affairs issues.

He said, "I wanted to go with Gary but he failed me." Grasmick voted for Donald Trump instead.

9:20 a.m.

Lines were long in some places, but few voters heading to the polls early Tuesday appeared to be encountering problems.

Presidential elections usually include sporadic voting problems, such as machines not working properly. Calls to Election Protection, a national voter helpline, included people reporting long lines as a result of machine problems in three precincts in Virginia. And election officials at a handful of precincts in Durham County, North Carolina, were using paper roll books after technical issues with computer check-in.

Ahead of the election, there was anxiety over whether voters would face problems. Republican presidential candidate Donald Trump said the election was rigged and Democrats warned that Republicans were planning to intimidate voters. There were also concerns about hackers disrupting election systems.

Donald Trump's eldest son says that his family will "respect the outcome" of a "fair election."

Donald Trump, Jr. told CNN's New Day Tuesday that he thinks his father "will remain involved somewhat" if he loses the election. He said he hopes that the energy surrounding his father's campaign "goes back to the people we are trying to fight for, the people who haven't had a voice in a long time."

He said, in retrospect, that "hopefully we shed some light on the process," and enabled people to speak their minds freely, "without being put in some basket, without being boxed in a corner."

Women across the United States are wearing pantsuits Tuesday in a show of support for Hillary Clinton.

Many were inspired by a Facebook group called Pantsuit Nation that has more than 2 million members. Some are also wearing white in honor of the suffragists who wore white when they fought for women's voting rights in the early 1900s.

In Alexandria, Virginia, Heather O'Beirne Kelly says she's wearing a white pantsuit, inspired by the Facebook group and organized efforts to get women to wear white to vote.

New Yorker Denise Shull tried to buy a white pantsuit on Amazon, but they were sold out. She's wearing a black-and-white suit to support Clinton, but also to symbolize "women making progress."

Bill Clinton said he's eager to be a political spouse, joking that he had "15 years of practice."
